This invention consists in; a new manufacture having therapeutical"properties, and usable in the same way as smokingtobacco in pipes or in, the format cigarettes. It consists in aproduct prepared according to the hereinafter described method Jfr'oin' plants of the Myrtooew in' which a notable proportion of eucalyptol and/or p perotone is contained. The leaves of any of the numerous members of the e wolypt species in which eucalyptol and/or plperotone are contained are usable as the raw materlal for the product. The aromaand the therapeutlcal value vary according to the characteristlcs of the particular member which is used. Thus, a. delicate aroma combined with a h gh therapeutical value is obtained in a product manufactured from Eucalyptus citm'odora, whilst E. dives produces a heavier tasting and stronger smelling product also having notable therapeutical value. The selection of the raw material best appropriate for a particular demand depends upon the aroma and taste which appeals to the deslres of the In ractice, the varieties which are of best uti ity are E. citm'odom, E. dives E. plwllandm, E. Australicma, E. glob and E. olyb'racteaz.

This roduct has isplayed marked therapeutical value when smoked b persons affected by catarrh and certain a ections of the respiratory organs.

The process of manufacture of this not is as follows The leaves of the selected eucalypt are taken fresh from the tree; adherent stems and woody matter and withered leaves and leaves which have been mutilated by insects and leaves which carry parasitic growths are separated out as waste; and the selected leaves are air dried or are dried by artificial heat, the drying being terminated before the stage is reached at which the leaves would become too friable to survive the subsequent operations on them. The leaves of distinct s ecies may be utilized separately, or the leaves from two or more varieties of eucalypts may be mixed in any desired proportion determined by their respective aromas, having regard to the particular character of final product to be obtained. Thus, the various varieties of E. dives may be mixed indifl'erently, or the mix may contain leaves of such species as E. phellandra, E. citfiodom, and E. globuhcs. The leaves prodrolls and crushed sufliciently to burst open 1 the cells andthey are then maceratedin a. weak aqueous solution of. glycerineand nitre (salt-petre) for, a period of 3 lio ursmo lfe' or less. only? enough liquor is used'to .efiect maceration, and] drained ofl liquor is reused for macerating further batches. The glycer me which is absorbed into the leaves functions as a hydroscopicagent which prevents drying out of the end product, and the saltpetre which is absorbed augments flagration of the end product so that it is made usable for cigarettes and for pipe smoking purposes. After maceration, the leaves are drained and placed in a pressure tight vessel and heated therein to bring up the temperature to a point not in excess of 200 F. orthereabouts. 100 F. may be regarded as a low temperature limit. The period of heat treatment is about three hours, more or less, and it is advantageous to move the leaves during the heating operation. A little molasses or honey may be used in the macerating solution'in addition to or as substitute for After treatment with liquor (and heat) a mass of the leaves is. packed in a mould and compressed. Large sound leaves should be disposed on the outer part of the mass to better ensure compactness of the pressed block. The leaves adhere sufficiently to remain in cake or block form almost indefinitely after removal ,from the press. The desirable pressure is in excess of two tons on the square inch; the pressure is maintained for an hour or more, and the moulds are heated, but not above 212 F. A sufficiently high temperature to boil off the moisture so as to'overdry the product is ob Ibo jectionable. After removal from the press,

the cakes or blocks are aged to cure in boxes or other protective containers for a period of several weeks. They may then be cut to z f il I. 1 3
